Byakuro can be persuaded, and should even be easily persuaded.
After all, in Satoru's Future Sight, as long as Kanoya could encounter it, there was a decent possibility of persuading Byakuro to become an ally by herself.
And indeed, that was the case.
Byakuro, with a lantern and blade in mouth, seriously began considering Shouka's proposal.
Although it didn't particularly like human Exorcists, the current situation was that both a human and a wolf were trapped in Songze, and this bizarre space was a common enemy for both of them.
When there is a clear external conflict, internal strife and Byakuro's personal dislikes can be compromised to a certain extent.
Moreover, the Exorcist girl said her Master was very powerful and was trying to rescue her...
Byakuro didn't know whether this was true or false.
But what if it were true?
Could this be an opportunity to escape from the trap?
